- Peripheral Nervous System (PNS)
is composed of the spinal nerves, cranial nerves, and part of the autonomic nervous system.
Its function is to provide communication from the brain and spinal cord to other parts of the body.
- Guillain-Barre syndrome
Idiopathic polyneuritis, acute inflammatory demyelinating polyneuropathy (AIDP), acute motor axonal neuropathy (AMAN), and acute motor and sensory axonal neuropathy
An autoimmune attack of either the axon or the peripheral nerve myelin.Acute, rapid segmental demyelination of peripheral nerves and some cranial nerves
- legs and spread to the arms and upper body. This is referred to as an ascending paralysis.
in demyelinating GBS, symptoms typically begin in the?
- mylen
installation for cells, helps with conduction of impulses from cell bodies to nerves towards the brain or spinal cord
- axon
the extension of a neuron/nerve cell, carries the impulses
- Stages of Guillain-Barre Syndrome
The acute or initial period (1 to 4 weeks) The plateau period (several days to 2 weeks) The recovery phase (gradually over 4 to 6 months, maybe up to 2 years) 1 / 2
- yes but can take 4-6months to years and have permenant damage
is guillan barre reversible
- Respiratory or gastrointestinal infection Vaccination
Pregnancy
Surgery
what are the 4 main causes of guillan barre
- Most common GI infection is campylobacterjejuni
Epstein barr, influenza or CMV are most common resp infectons
what are the most common infectionous organisms that cause guillan barre
- cell-mediated immune attack on peripheral nerve myelin proteins
guillan barre results from a?
- amino acid
Infectious organism contains an that mimics the periph- eral nerve myelin protein.
- Segmental demyelination
Antibodies attack the myelin sheath that surrounds the axons of the peripheral nerves which causes
- schwann
in Guillain-Barre, the cell is spared
